Jennifer Aniston to Appear on 30 Rock

Jennifer Aniston will guest star on an episode of 30 Rock this season, her publicist confirmed to the Associated Press. It will be the actress’s first appearance on an NBC sitcom since Friends went off the air in 2004.

“She is shooting now,” a source tells E! Online. “We are not giving any specifics on her character.”

Aniston, 39, has been taking mostly film roles since Friends wrapped four years ago after 10 seasons. She did appear in one episode of the FX series Dirt, a show about celebrity journalism starring Aniston’s Friends-mate — and real life pal — Courteney Cox, in 2007.
